I've seen a few different numbers, but this source puts the number at at least 100 billion galaxies in the observable universe.

I used the word factorial looking at some super basic IRL scenario and everyone gave me one of those, "You're a fucking idiot" looks and scoffs...

This was maybe 2 weeks ago at most.

Thanks.

You have a chance of 1/10 to pull the first marble, then a 1/9 chance to pull the second, a 1/8 to pull the third, ....
In the end you have to multiply all factors and get 1/10*9*8*...*2*1 = 1/10! = 1/3628800 or 0.000000276%

Nice, thanks.

The observable universe contains about 3 to 100 × 1022 stars (30 sextillion to a septillion stars), organized in more than 80 billion galaxies, which themselves form clusters and superclusters.

In short, your life matters very little in comparison. So does mine.
Let's all get depressed now.

Not by a long shot, but that is likely a pretty conservative estimate for the number of stars in our own one galaxy, the Milky Way, to which we have more galaxies in the universe then our galaxy has stars.
Also- Why was I suddenly reminded of the Drake Equation when you asked that =p
Perhaps because you were asking the odds for the perfect conditions.

You're getting there. :P
@ Saras - Thanks. And holy crap at this image. That makes more sense.
